2021年8月1日 1. Antimony – general aspects. Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3. 121 Sb (57.21% abundance) and 123 Sb (42.7% abundance) are the two stable isotopes of antimony. Antimony can possess different oxidation states (such as +5, +3, 0, −3 and −5), but
